Jedi Knight William force pushes a rock so the attention of the Sith and the Sith Troopers is diverted. A disguised Republic Trooper ( White would just blare their presence in a swamp ) runs up and fires, to take out the Sith Troopers so that William and the Sith can have an even fight. Also you can see the smuggler Jim Horn. More on him later.

Knight William and the Republic Trooper.

Here you can see Jim Horn (I had a short time to brainstorm his name, so hes Jim Horn :D) a smuggler that was secretly going to defect to the Republic and offer his services. However the Sith caught on and took him prisoner when he was trying to get to the Republic's lines.

Overhead view. Here you can see I knocked over a plant and did't realize it was supposed to go in the mud, cause I was photographing in a hurry. You can see that in this pic and the next.
